If I boot my machine, running openSUSE 11.1 x86_64 with 2.6.27.25 kernel, it reaches the graphical login prompt then immediately performs an orderly shutdown, just as if I’d asked it to shutdown by hand.
This happens if I boot into failsafe mode
This happens if i boot into init level 3.
It does not happen if I boot into single user mode init level 1.
It does not happen if I use the rescue disk.
It managed a complete fsck of 6 disks once, and seems happy in single user mode, staying up for at least half an hour until I shut it down myself, which rather rules out overheating.
This started some weeks ago, and was rare enough for me to think I’d hit a key by mistake, but now it seems permanent.
This is out of my comfort zone, but at least I can get into the machine at init level 1. Any help will be much appreciated, sincerely.
It shuts down before I can login, but stays up if I boot in single user mode.
My boot parameters are the defaults AFAIK, I just append a space and the digit “1” to enter single user mode.
I’ve fitted a brand new shiny expensive Corsair 450W power supply so I really don’t think it’s a hardware issue. If it was, it wouldn’t explain why the machine is happy when in single user mode. The BIOS would make a horrid noise before the thermal cutout was triggered - overheating isn’t apparent.
I’m wondering if something is happening with either “at” or “cron” OR that my problem co-incides with my recent update to kernel 2.6.27-25. I see from another machine that 2.6.27-29 is available.
Just ahead of that event in the log, I see that there is an ACPI resource conflict between the w83627hf (the chip that does the sensors on my mobo) at 0x295-0x296 and something called ACPI region IP_, also at 0x295-0x296. I tried re-running sensors-detect and it finds the w83627hf at 0x290.
So I’m beginning to suspect the kernel update has b0rked something.
An example from /var/log/messages on my machine from before I disabled lm_sensors:
